 ABSTRACT

In plant breeding programs development of crop cultivars with superior performance has always been the prime objective. F3 population (100) of the cross between DBW17 x WH1105 of wheat were characterized on the basis of 11 morphological characters. The genetic variability studies in F3 generation indicated high mean and wide range for all the traits under evaluation. PCV for all the traits was found higher than GCV. High GCV and moderate PCV were recorded for grain yield per plant, biological yield per plant and number of tillers per plant. Plant height, number of grains per spike, number of spikelets per spike and days to heading exhibited high heritability. GA as 5% means was highest for grain yield per plant followed by biological yield per plant, number of tillers per plant and number of spikelets per spike. Grain yield displayed significant correlations with biological yield per plant, spike length, number of spikelets per spike, spike weight, 100 grain weight, harvest index, number of grains per spike and number of tillers per plant but days to heading and plant height were non-significantly correlated with grain yield per plant. The D2 analysis showed 100 F3 plants including parents in 7 clusters and cluster 5 was potential contributor of 100 grain weight, biological yield per plant and grain yield per plant and this cluster was the most important for selection. Cluster 7 was potential donor of number of grains per spike, number of tillers per plant and also short height plants thus can be used for dwarf trait selection. This suggested better scope for selecting superior transgressive segregants in F3 population.
